LIFTING-JAGK.

Application filed April '17, 1913.

Specification of Letters Patent.

Patented Feb. 24:, 1914.

Serial No. 761,828.

To all whom it may concern Be it known that 1, MIKE LUTENBERGER, a subject of the King of Hungary, residing at Blocton, in the county of Bibb and State of Alabama, in the United States of America, have invented certain new and useful Improvements in Lifting-Jacks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in combination lifting jacks and more particularly to that class of lifting jacks carried by a car for replacing the car upon a track; the object being to provide a lifting jack which is so constructed that the same can be tilted and inclined in either direction in order to force the car laterally at the same time it is being raised whereby the car will be forced back upon the track.

Another object of the invention is to provide a jack which is so constructed that the same can be used for operating a brake or for winding a cable for drawing the car along the track or back into position upon the track.

Another object of the invention is to pro-' vide a jack which is exceedingly simple-and cheap in construction and one which can be attached to either end of the car in order to operate thereon so as to replace the car at either end; said jack being provided with means at its upper end for supporting the same, which is slidably mounted upon the car so as to allow the same to be shifted in order to tilt the jack or throw the same at any angle desired for replacing the car.

A further object of the invention is to provide a jack which can be operated by a ratchet or by a bar; the lifting screw being provided with a swiveled foot for engaging the surface.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawingsFigure l, is a side elevation of a car showing the application of my improved construction of combination lifting jack thereto; Fig. 2, is a detail top plan of a car showing the lifting jack in position; and Fig. 3, is an end elevation of the car showing the jack in dotted lines in lowered position, the car being inclined and raised for throwing the same back into position upon the track.

Like numerals of reference refer to like parts in the several figures of the drawmgs.

In carrying out my improved invention I provide the car 1 with tubular bearings 2 and 3 which are formed exactly alike; each bearing being secured to the underside of the bottom of the car to one side of the coupling member. Mounted in the bearing is a support 4: which is provided with a head 5 having a threaded bore to receive the lifting screw 6; the upper end of which is provided with transverse bores 7 to receive a tapering lever 8 by means of which the screw can be rotated. The lower end is provided with a foot 9 which is swiveled thereon in order to allow the same to have a universal movement. In order to provide means for rotating the screw quickly, I provide the same with a ratchet 10 which is engaged by a pair of spring-pressed dogs 11 carried by a lever 12; pins 13 being provided for holding either of said dogs out of engagement with the ratchet in order to allow the screw to be rotated in either direction. The lever is preferably provided with a bifurcated head 14 between which the ratchet 10 is arranged and in which the dogs 11 are pivotally mounted and held into engagement with the ratchet by the springs, as clearly shown.

The lifting screw 6 extends through an eye 15 carried by a substantially inverted U-shaped clip 16 which is arranged over the upper edge of the end of the car as clearly shown in Fig. 1; said eye forming a bearing for holding the screw in its proper position. It will be seen that by shifting the U-shaped clip along the upper edge of the car, the lifting screw can be thrown at an angle in either direction so that when forced into engagement with the tie or road bed and rotated, the car will be lifted vertically, and at the same time, moved laterally so as to force the same back upon the track after it has been derailed. By this construction, it will be seen that a lifting jack is so mounted that it can be easily and quickly detached or attached to either end of the car and in such a manner that the same can be quickly placed into operation so as to lift the car back into position upon the track. When the U-shaped clip 16 is moved along the upper edge of the car, the support 4 moves in the bearing in order to allow the screw to assume any angle desired.

The car is provided with a brake beam 18 carried by crank arms 19 fixed on the shaft 20 mounted in suitable bearings on the under side of the car; said shaft being pro vided with a crank arm 21 to which is connected a cable 22 normally supported by a bracket 23 upon the side of the car; said cable having a hook 2% at its end which is adapted to fit within a transverse bore 25 formed in the lower end of the lifting screw 6 and it will be seen that when the lifting screw is operated so as to reach the upper position by rotating the same downwardly, the cable will be wound thereon in order to apply the brakes to the car.

' In order to provide means for drawing the car along the track or for moving the same back into position after it has been derailed, I provide a cable 26 which is preferably carried by a bracket 27; said cable having a hook 28 adapted to fit within the bore 25 of the lifting screw and at its opposite end with a hook 29 adapted to engage the tie, as clearly shown in Fig. 5, so that when the screw is rotated, the cable will be wound thereon in order to move the car. While I have shown an additional cable for this purpose, it is of course understood that the cable 22 for operating the brake could be used.

F mm the foregoing description, it will be seen that I have provided a combination lifting jack in connection with a car which is so constructed that the same can be used for moving the car, operating the brake, or for lifting and shoving the car back upon the track whereby a car replacer is formed.

I claim:

1. The combination with a car provided with a tubular bearing at its end, of a detachablesupport pivotally mounted in said bearing provided with a head having a threaded bore, a threaded lifting screw working in said bore, a U-shaped member slidably mounted upon the upper edge of said car, and a bearing carried by said U- shaped member through which said screw extends.

2. The combination with a car provided with a tubular bearing at one end thereof. a support pivotally mounted within said bearing having a head provided with :1 threaded bore, a lifting screw working through said bore, a swiveled foot carried by said lifting screw, a U-shaped clip mounted upon the upper edge of said car, an eye carried by said clip through which said screw extends, and means for revolving said screw.

3. The combination with a car provided with a horizontally disposed tubular bearing on the bottom thereof, a cylindrical support pivotally mounted in said bearing and extending outwardly therefrom at one end having a head provided with a threaded bore, a. lifting screw mounted within said threaded bore having a swiveled foot at its lower end, a U-shaped clip slidably n1ounted on the upper edge of said car provided with an eye to receive said lifting screw, and means for revolving said screw.

In testimony whereof I afiix my signature in presence of two witnesses.
